Groundwater Recharge

Artificial recharge is the process of helping the natural recharge process by guiding water back into aquifers under controlled conditions using special recharging wells. Canals and irrigation furrows can be used to assist the water’s natural flow back into the ground. Water can also be pumped from a dewatering system into a recharge location and then injected back into the ground. The water is purified before injection to prevent clogging of aquifers.

Direct Surface Recharge Technique

This is a process by which excess water is collated and passed into a lake or shallow water body while it naturally sips into the earth. The effectiveness of this method is dependent on the porosity and permeability of the underlying rocks which the water is passed unto (University of Pisa).
